The Brazilian Federal Senate election for Minas Gerais is scheduled to take place on October 4, 2026. This market will resolve according to the candidate who wins the second-most valid votes of any candidate at the specified election. Candidates will be primarily ranked by order of valid votes won. If two or more candidates are tied for any position, ties will be broken by alphabetical order of the candidates’ listed full names as they appear in this market. This market will resolve to the candidate that occupies the second-highest finishing position after applying this ranking. If the result of this election isn't definitively known by June 30, 2027, 11:59 PM ET, the market will resolve to "Other". This market will resolve based on the result of the election, as indicated by a consensus of credible reporting. If there is ambiguity, this market will resolve based solely on the official results as reported by the Brazilian government, specifically the Superior Electoral Court (Tribunal Superior Eleitoral, TSE) (e.g., www.tse.jus.br/eleicoes/resultados-eleicoes).
Recent July 2026 polls from Quaest/Genial and Real Time Big Data show a fragmented Minas Gerais Senate field ahead of the October 4 vote for two seats, with Marília Campos (PT) leading first-place intentions at 18–24% while Carlos Viana (PSD), Marcelo Aro (PP), and others trail closely behind. Aécio Neves (PSDB) has withdrawn, further dispersing support among center-right and conservative contenders. The wide field of 17 registered candidates, limited name recognition for many, and absence of a dominant second-place contender sustain tight trader pricing around Viana and several others near even odds. Upcoming campaign launches, additional surveys, and coalition moves before election day could consolidate preferences and widen gaps in second-place probabilities.
